Quadratic formula levels for Smiley's Adventure
Copyright 2006 by Patrick Davidson

The .89z and .9xz files contain two levels to play using Smiley's
Adventure version 0.26 (or above) on the TI-89, TI-92 Plus, and
Voyage 200.  Far better than a quadratic formula program which
just tells you the answer, these levels are much more fun, but
also help you to learn by showing the formula.

Due to the screen size, these levels will probably look better on
the TI-92 Plus and Voyage 200 than on the TI-89.
